To all whom. it may concern:

....---.l3e.it known that-I, Gsones. .l. Soeer-z, a. citizen of -thc '1] nited Slates, residing at Hanson, in the county of Yunkionaud State of South Dakota, have invented certain new and useful Improvements in 'lransrnission- Gean'ings, of which the iollowingis a specification.

The present invention relates to improvements in tnmsrnission gearing gf tliat type which is commonly employed in connection with automobiles or like devices in which it is desired to impart motion from a.

constantly rotating shaft to a driven part, both na veriable speeds with relation to the shaft and in a reverse direction to that oi the shalt.

The object of the invention is to provide a device which will accomplish this result in-a very efiicicht nuinner with compamtivcly little loss by friction, and

which is at the sometime very compact in its structure. For a fulldeseription of the invention and the merits thereof andalso to acquire a knowledge of the details of construction of the means for effecting the result, ref crence is to behnd to the following description and accompanying drawir1gs,'ii i which:

Figure lis aside elevationof the transmission genring; Fig. 2' is a longitudinal sectidnal view through the some; Fig. 3 is a; transverse sectionail view on the line z-a: oi Fig. 2; and, Fig. 4 is a longitudirml sectional view on the line'y-y of Fig. 2. f

Corresponding and like ports are reierredto in the following description and indicated in all the views of' the'drawings by the some reierence characters.

The numeral 1 designates the driving shaft which is connected directly to eny suitable source of power and which revolves constantly in the same direction and at the some speed. The case 2 is keyed upon, or other wise rigidly connected to the shaft 1 in such a manner as to always turn therewith. This case, in the present instance, comprises a central disk 3 which is rigidly connected to the shaitand which is provided at its periphery with annular flanges 4' which project outwardly in opposite directions and have their edges turned inwardly, as seen M1 5. Openings 6 nreforrned in the plate 3 at diametrically opposite points, and a pair of brackets 7 is holtml or otherwise connected to the plate so as to projectoutwnrdl y on both sides of each of the openings 6. A shaft 8 passes loosely through eachbt the openings 6. and has its opposite ends journaled in the brackets 7-. Four gear wheels 9, 10, 11

and 12 of -various sizes are keyed upon each of the shafts 8, two of the gear wheels being placed upon mieh side.

end of the sleeve 14 is located the sprocket wheel 16 oianyother suitable meains fortransniitting power to the rear axle or part being driven. In a'somewhat similar mannctythe sleeve 13 is provided at its inner end with the gez r wheel 17 which meshes with and issomewhot smaller than the gear wheels 10 upon the shafts 8. A drum 18 is connected to the outer portion ofthe sleeve 13 so is to revolve with the said 'sleevqftho said drum comprising a disk 19 having the thereof formed with an outwardly flange 20 around which the brake bendfll pesssli' f .A drum 22 having the gee'r wheel23 connected thereto is loosely mountedjupon thersleveltso use the said gear wheel meshcswith'zind Mspprokinistely the same size as the gear wheels 12 iup o'li 8.

A band eeni the two 18 and 26 so that hyforeingthetwodrums towgr'ded h other, they um be loclged simultaneously: Inorderto provide ineansgforlforcing the drum 18 toward the 'dnmi26, to the projecting end of the sleevfii'l ond s series "of curved levers 30 pivot dly mounted uponithesaid collar. The outer end of each of the levers ill) engages with a conical member 31 slidably mounted upon the driving shait 1, while the opposite 'of fich of the curved leverseugages with the of an annular projection 32 upon the platellfh j W-ith this construction, it will be epparent thet when the conical member 31 is forced inwardly, as can be readily accomplished, in any suitable'manneras by alever, the curved levers 30 will act to'i'orce the drum 18 toward the drum 26 rind the two drums will be locked"togetherf v 1 By the proper manipulation of the parts described, it is possible to secure 3 toward speeds" and a. reverse. When the bmke bnnd 25 "is tightened sojas'to hold the .drum 22 in a fixed position, the wheels 12 will revolve about the gear wheel 23 as the case 2'turns with the drive shaft- 1 iind in the presentinstancc, the shafts S will make one turn in the same direction for every turn of the drive shaft lfsince the gear wheels 12 and 23 are of approxinuttely the same size. These shafts S will transmit motion through the gear wheels 11 run] 16 to the sleeve 14 and will tend to cause the same to reupon one side of the case, the said brake drum having an operative connection with one of the gear wheels and,

being formed with a peripheral flange extending over the corresponding annular flange upon the case, a second brake drum upon the'opposlte side of the case, the second 10 mentioned brake drum also having an operative connec= v tion with one of the gear wheels and being formed with a peripheral flangeextendln'g over the corresponding annular flange upon the case, a third brake drum-having nn operative connection with one of the gear wheels and designed to be moved longitudinally of the" shaft so as to be locked to the second mentioned brake druni, and means for locking the brake drums in a fixed position.
